LOUIS TILLIERS, OF MOTT HAVEN,V NW YORK.

VISE.

Specification of Letters Patent No. 32,093, dated April 16, 1861.

To all whom fit concern: k

Be it known that I, LOUIS TILLrEns, of Mott Haven, Testchester county, in the State of New York, have invented, made, and applied to use a new and Improved Vise; and I do declare the following to be a full, clear, and correct description ofthe same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which- Figure l. is a view of my improved vise when used as the ordinary vise.- Figs. 2, 3, and 4. are views in which the capacity of the vise to grasp metal or substances of irregular forms, is illustrated. Fig. is a sectional view, showing the means employed by me to adjust the front jaw.

In the drawings, like parts of my invention are designated by similar letters of reference.

To enable others skilled in the art to make and use my invention I will speak of its con struction and Operation.

It is well known that much difficulty has been heretofore experienced in grasping in a vise provided with stationary jaws, irregular surfaces of iron or metal, and that it has been usual in such cases to hold the metal rmly by pieces of metal or wedges placed between the jaws and the metal or iron.

C. B. Clark in 1858 obtained a patent for improvements in vises, and although a movable jaw hadbeen employed prior to his invention, we may safely regard Clarks as the best vmovable jaw vise as yet made but in Mr. VClarks vise but one movable jaw or but one jaw that will incline itself is employed, and .only at an angle of from 50 to 8.

With a view to produce as perfect and complete a vise as possible and one that shall be capable of accommodating any substance no matter how irregular its form and angle I propose to construct a vise having both its jaws automatic and yet so regulated that the vise shall readily answer all the purposes of the ordinary vise when desired. For this purpose I attach to the vise A, the two jaws B and C, the former of which Operates as follows-this jaw B is made movable that it may present itself either vertically Or angularly: and when angularly, the summit of the angle can be thrown upward Or turned downward as required. To turn the jaw down Or throw the same up, the jaw B4 grooved On its back as at a2 Fig. 5, and plays freely upon the roller c, attached to the j jaw-support (Z, and over which the grooved portion of the jaw B is placed, and to which it is attachedby screws e e, at the ends of the roller c. The second jaw C is rendered movable also that it may always present itself vertically or parallel with the front jaw B or at an angle to it. This jaw C assumes the Obliquity necessary to firmly grasp the object.

'In Order that the jaw B may be held iirmly in a vertical position, the jaw B being hinged to the roller as shown is regulated by means of set screw y, by means of which the face of the said jaw B is held in a vertical position or thrown into an oblique one, when desired-while the aw C being provided with a swivel joint, allowing said jaw to move vertically is held lirmly in any required position by set screw Z.

TO illustrate how perfectly capable of grasping and holding firmly a substance no mattei' how irregular its form, I have shown on the drawings hereunto annexed three views, in which irregular forms of metal are shown firmly grasped and held by the movable jaws B and C. In one case, :a cone is shown, which can be grasped between the jaws B and C, whether its base shall be at its right or left end, up or down, Or even obliquely.

I am not aware that any vise has yet been i constructed capable of accommodating a piece of metal with four irregular sides.

Having thus set forth my invention, what I claim as new and desire to secure by Letters Patent is.

A vise, in which one limb has the jaw B hinged with a vertical movement and the other with the jaw C with a horizontal movement, the whole arranged, constructed and operating as and for the purpose set forth,-

LOUIS TILLIERS.

In presence of- A. SIDNEY DOANE, GEO. T. GORDON.
